PicArts' biggest new feature is Remix, which adds a lively dimension of social photo editing to the app. In this manner, the searchable library of available stickers grows daily. You can share your stickers with the PicsArt community (as well as use any publicly shared stickers), or keep them private. On the other hand, when you add a sticker to another picture, you can use the blend tool to try to edit the edge. While using the Cutout tool is great fun, we found that the lack of feathering control and the clumsiness of using your fingertip to create the cutout can sometimes result in a jagged edge (there’s no auto-selection tool). Now you can create custom stickers from your photos, such as a sticker of a flower you photographed, or your friend's head. PicsArt has long had a nice selection of stickers. We found ourselves enjoying the playfulness of the easy-to-control options. With just some taps and drags, you can quickly swap images, change the relative sizes of the image placeholders, zoom and pan around to get just the right view of the image within the collage and experiment with borders, text, stickers, effects and color. Similarly, the Collage module offers a great variety of templates, including delightful combinations of nonrectangular image placeholders. MORE: The Best Photo Editing Apps for iOS and Android
